And a proposal to authorize $15 million for improvements to park and recreation facilities won by a 70 percent to 30 percent margin.

A proposition to reauthorize the Crime Control and Prevention District, which designates a portion of existing sales tax revenue for community safety initiatives, won with 81 percent of the vote.

About 2,700 residents cast ballots. Cedar Hill's population is about 48,500.

Some of the bond items would help fund projects central to Cedar Hill's City Center plan, which aims to revamp a large part of the downtown area into a more walkable, mass transit-friendly space.

The bond referendum was the first in Cedar Hill since 2003, when voters authorized $19.9 million toward a new city hall, as well as $4.6 million for an expansion of the existing library. The library expansion never took place because of a downturn in the economy that wouldn't have allowed for the completion of the project without a tax increase, City Manager Greg Porter said.

City officials haven't decided where the new library facility will be -- whether on the site of the current facility or somewhere else. In addition to extra meeting spaces, the new library also could become the new home for the Cedar Hill Museum of History.

An investigation by The Dallas Morning News found that some City Council members voted to approve parts of the City Center plan without disclosing that they own properties that could benefit.

City officials disputed the Morning News account by issuing a statement on the city's website.

"In all of their disclosures, council members at all times followed state law and followed the advice of staff and legal counsel," the statement read.
